How to Replace the Battery Pack in Your Tool
Tap each step to tick it off as you go. Battery position and lockout controls differ by tool, which is why your tool manual is worth a look too.
- 1Stop and lock the toolRelease the trigger and let the tool stop. Then engage the tool’s lockout, such as the center position on a drill/driver switch.
- 2Release the latches and remove the old packPress the battery release latches and pull the pack out. Keep your fingers off the trigger.
- 3Insert the new packSlide a compatible 18V ONE+ pack in using the orientation shown in your tool manual, and push until it seats.
- 4Check that it is securedMake sure the latches have snapped into place before you use the tool.
Release the trigger and try again; RYOBI says this resets a tool that stopped during use. If the tool still does not run, recharge the pack. A hot pack may wait on the charger until it cools to an acceptable temperature. If the pack still will not charge or run, contact RYOBI support.
